JOHN HENRY OAIRNOROSYS, TORONTO, CANADA, ASSIGNOR TO GEORGE F. BURTON, OF SAME PLACE.

ADVERTISING DEVICE.

SPECIFICATION forming part of Letters Patent No. 510,157, dated December 5,1893.

Application filed December 24, 1892. Serial No. 456,284. (No model.)

To all whom it may concern.:

Be it lknown that I, JOHN HENRY CAIRN- OROSS,ot` the city of Toronto,in the county of York, in the Province of Ontaria, Canada,

have invented a certain new and useful Improvement in Advertising Devices, of which the following is a specification.

The object of the invention is to provide a simple device by which advertising cards and ro similar devices may be readily held in a conspicuous position and as easily removed and it consists in the peculiar construction, arrangement and combinations of parts hereinafter more particularly described and then `I5 definitely1 claimed.

In the accompanying drawings-Figure 1, is a perspective inside view showing my device applied to the root' of a street car. Fig. 2, is an enlarged detail of the frame with a zo portion of the molding in section. Fig. 3, is a sectional detail of the latch. Fig. 4, is a detail of the key for unlocking the latch. Figs. 5 and 6, are alternative forms of molding for holding the frarnein position.

z5 On the surface of the frame A, I print or otherwise place the advertising matter. On the one edge of the frame A, (preferably the bottom) I form a groove a, as shown in Fig. 2, a projection b, as shown in Fig. 5 or a clip 3o d, as shown in Fig. 6.

B, is a molding connected to the surface on which it is designed that the advertisement should be displayed. On this molding B, I form a beading C, when it is designed to en- 3 5 gage with the groove a, or the clip d; or when the projection b, is used on the frame A, I form a groove e in the molding B. This holds one end of the frame A. The other end fits against a molding D and in order to lock the 4o frame in position, I provide a spring latch E, either ixed to the frame A, as shown in Fig. 2, or connected to the molding D. In the former case the latch will engage with a groove made in the molding D, as indicated in Fig. 2, or if the latch is connected to the molding, it will engage with a groove made in the frame A.

In order to put the frame in position, the grooved end or its equivalent is placed on the molding B, andthe other end of the frame 5o pushed in behind the molding D, the spring latch E, springing past the molding and locking the frame in position. The spring latch consists of the bolt g which is normally kept in the position shown by the spring lo. It is operated by a dog I which is secured to the key spindle Z and which has two tails 2' which act on the lug g projecting from the bolt.

I do not claim anything peculiar in the spring latch or in the key F, but show them 5c in the drawings as illustrating the practical way of accomplishing my purpose.

In order to prevent the frame A, rattling,

I place steel springs L or pieces of rubber or other material in such a position as to hold it steady.

What I claim as my invention is A frame for holding the advertising device and having a grooveor projection formed on or connected to one edge and arranged to en- 7o gage with a projection or groove formed on or connected to the surface on which the frame 4 is placed, in combination with a spring latch arranged to lock the frame into its holding device, and a spring bearing on said frame and surface whereby the frame is kept from rattling the whole being arranged substantially as and for the purpose specified.

Toronto, November 2l, 1892.
